Abstract (en)
A method, according to an embodiment, is provided for correcting pixel data provided to a display apparatus. The display apparatus, according to an embodiment, includes a display panel having a plurality of pixels and a light source module having a plurality of light-emitting blocks. The method includes determining a pixel luminance that is a luminance of light provided to each of the pixels; and generating correction data to correct the pixel data, the correction data being generated based on the pixel luminance and a maximum emission luminance that is a maximum luminance of the light emitted from each of the light-emitting blocks.
